All I can say is WOW about this machine. I recently sold an Original Rev A MBA on craigslist for 500 that I never really used... got tired of the heat, the fans running, and the short batt life. I also have a Late 2008 MBP that runs great since I just put a 240g SSD in it. Now after using this new MBA, I may go ahead and sell the MBP because I am thinking I wont use it anymore!!! This 2012 Air creates no heat, no fan noise, light as a feather... I debated getting the 13" rMBP but the screen on the Air is almost as good, but I opted for the lighter weight. Stereo speakers YEA !!! but a little weak, but then I install the BOOM app, again WOW. I looked at the 11" but was worried that the battery life. Also previous to getting the Air, I did convert to the dark side and tried two different win8 touch screen laptops. This was a mistake, I think win8 is ok, but the Asus had terrible screen quality. Next was the Samsung series 5, better screen but terrible terrible trackpad. I realized then that I was going to have to spend more than $700ish. So it was back to Apple, I would rather have a great trackpad and loose the touchscreen. The only thing that would make this machine better would be an LTE connection. I have a 3gen iPad with unlimited ATT LTE, If I could move that data to the Air I would ditch the iPad. Great Machine.
